ok then, so FK510 it is.. now looking for tyre shop with good price. I heard from a friend of mine, there is 1 shop in kota kemuning give cheapest tyre price he ever found.Falken FK510 is quite highly recommended. GY F1A5 should be around PS4 price. Since you mention not hardcore, V12Evo2 and FK510 is very good already. Outright performance then PS4 or F1A5
